A transport aid with a quick assembly-disassembly function and a width adjustment function, comprising:
- a left support member formed by welding a plurality of metal tubes, comprising:
- a left armrest part disposed on a top edge of the left support member, and comprising a top side configured to place a sitting person's left hand, a retractable mechanism disposed inside, a rotatable connector pivotally connected to an inner side or an outer side thereof adjacent to a front end thereof and engaged with an end of a rotatable handle, wherein when the rotatable connector is rotated, the retractable mechanism is driven to retrieve two first cable belts or ropes exposed out of a bottom side of the left armrest part, into the left armrest part, and the exposed parts of the two first cable belts or ropes become longer, or when the rotatable connector is rotated, the retractable mechanism is driven to release the two cable belts or ropes from the left armrest part, the exposed parts of the two first cable belts or ropes become shorter, wherein each of the plurality of first cable belts or ropes comprises a first quick connector disposed at an end thereof away from the left armrest part;
- a left roller part integrally formed by welding a plurality of metal tubes, comprising rollers pivotally connected to a bottom side thereof adjacent to a front end and a rear end thereof, and comprising a top side connected to the bottom side of the left armrest part by a plurality of vertical support rods, so that the left roller part and the left armrest part are spaced apart from each other by a predetermined vertical distance;
- a right support member formed by welding and assembling a plurality of metal tubes, and comprising:
- a right armrest part disposed on a top edge of the right support member, and comprising a top side configured to place the sitting person's right hand, other retractable mechanism disposed inside, and other rotatable connector pivotally connected to an inner side or an outer side thereof adjacent to a front end thereof and engaged with an end of other rotatable handle, wherein when the other rotatable connector is rotated, the other retractable mechanism is driven to retrieve two first cable belts or ropes exposed out of a bottom side of the right armrest part, into the right armrest part, and the exposed parts of the two first cable belts or ropes become shorter, or when the other rotatable connector is rotated, the other retractable mechanism is driven to release the two cable belts or ropes from the right armrest part, the exposed parts of the two first cable belts or ropes become longer, wherein each of the plurality of first cable belts or ropes comprises a first quick connector disposed at an end thereof away from the right armrest part;
- a right roller part integrally formed by welding a plurality of metal tubes, comprising other rollers pivotally connected to a bottom side thereof adjacent to a front end and a rear end thereof, and comprising a top side connected to the bottom side of the right armrest part by a plurality of vertical support rods, so that the right roller part and the right armrest part are spaced apart from each other by the predetermined vertical distance;
- a chair seat comprising second cable belts or ropes respectively disposed at left and right sides thereof adjacent to front and rear edges thereof, and each of the plurality of second cable belts or ropes comprising a second quick connector disposed at an end thereof away from the chair seat and configured to integrally engage with one of the first quick connectors corresponding thereto, so that the chair seat is swingably suspended between and below the left armrest part and the right armrest part stably;
- and
- two horizontal assembly frames formed by welding at least one metal tube, and comprising ends pivotally connected with parts of the vertical support rods which are adjacent to bottoms of the vertical support rods, and respectively between the left armrest part and the left roller part, and between the right armrest part and the right roller part, wherein other ends of the horizontal assembly frames are mounted with each other, and tightly packed by a quick packing connector (PC), so that the horizontal assembly frames are assembled and combined with each other to form a horizontal bottom support member.
